    摘要： In an optical gain equalizer according to the present invention, a plurality of etalon filters 1 and one ore more fiber gratings 2 or dielectric multilayer filters 3 are arranged in line, and a beam of light externally applied is passed through the etalon filters 1 and the fiber gratings 2 or dielectric multilayer filters 3 and outputted to the outside, and the etalon filters 1 have sinusoidal wave loss characteristic of the same amplitude and period as those of the term obtained by Fourier series expansion of the loss wavelength characteristic for gain flattening, and the one or more fiber gratings 2 or dielectric multilayer filters 3 compensate the ripple component remaining as the difference between the loss wavelength characteristic for gain flattening and the loss wavelength characteristic owing to the etalon filters 1. An optical amplifying device 14 is constituted by combining an optical amplifier 5 with the optical gain equalizer 4. A wavelength-division multiplex transmitter is constituted by using the optical amplifying device 14.

    摘要： A process for the production of a carbonyl compound such as acetic acid by reacting a carbonylatable compound such as methanol with a carbon monoxide in the presence of a carbonylation catalyst containing a noble metal complex supported on a porous, cross-linked vinylpyridine resin at a temperature of 140-250.degree. C., a carbon monoxide partial pressure of 7-30 kg/cm.sup.2 and a hydrogen partial pressure of 0.1-5 kg/cm.sup.2 to obtain a liquid product containing the carbonyl compound and an unreacted CO-containing gas product. The water content and the carbonylation degree of the liquid product within the reactor are maintained at 0.5-10% by weight and 0.5-0.9, respectively, The carbonyl compound is separated from the liquid product in a flasher and/or a distillation tower formed of titanium or a titanium-palladium alloy. The liquid product is introduced into a pressure reducing valve and then mixed with the CO-containing gas product before being fed to the flasher and/or distillation tower.
